Abstract

L'invention concerne un anneau de protection partagé à voies de transmission optique comportant de multiples noeuds. Ces noeuds intègrent une fonction de commutation optique ou crossbar permettant d'effectuer la commutation dans l'anneau assurant la commutation de protection des noeuds d'extrémité, pour les longueurs d'ondes pouvant être insérées et extraites. Ces noeuds comprennent également un sélecteur de voies optiques non intrusif au moins sur chaque voie de travail, côtés insertion et extraction du noeud. Selon cette invention, un sélecteur est toujours présent en tête de ligne, où le trafic est introduit dans l'anneau, et en queue de ligne, où le trafic quitte l'anneau, de façon à pouvoir déclencher la commutation de protection du noeud d'extrémité mise en oeuvre par les noeuds de tête et de queue. Cette commutation est déclenchée en cas d'absence de signal approprié uniquement en queue de ligne, mais pas en cas d'absence de signal approprié à la fois en tête et en queue de ligne, ce qui évite toute commutation de protection inutile.
